An LTH structure specifies for each course:

  • The manner in which a course is expected to be taught
  • The associated credits
  • The number of hours a student is expected to devote each week

Each course has an associated credit and a LTH structure. The credit assigned for a course is determined by the LTH structure specified for that course.

HHands-on activity or project1 credit per 2 hours of hands-on or project activity2 hours for every 2 hours of hands-on activity

An example:

  • A course with an LTH of 2-1-2 will have 3 credits, and will typically require a student to spend 11 hours/week,
  • A course with an LTH of 3-0-0 will have 3 credits, and will typically require a student to spend 9 hours/week,
  • A course with an LTH of 3-0-2 will have 4 credits, and will typically require a student to spend 13 hours/week.


  • A lecture is the traditional delivery by the instructor, while adequate opportunity for students to ask questions, raise doubts or react to instructor's points is also provided. The extent of interaction will depend upon the instructor, the class size, and on the subject being taught.
  • A tutorial session is wholly devoted to resolving doubts, helping students to solve problems, or in some cases discussing case studies. Students are expected to contribute to the discussion in a significant way. Each session will involve no more than 20 students.
  • Hands-on activity takes place in a laboratory at appointed dates/times, where the student is expected to successfully complete an assigned hands-on experiment, or successfully design/assemble/build an assigned sub-system, under supervision of an instructor, and submit a report before a specified deadline.
